Improving Administrative Data Quality on Tourism Using Big Data

National Statistical Institutes (NSIs) have been using the Administrative Data for official statistics production for many years. However, they are characterized by typical errors of the source (e.g., coverage, delay in data registration) that could be solved by integrating other sources. The study shows how the use of Big Data can partially solve some of the errors. Particularly, the information about tourist accommodation obtained through web scraping, was integrated with regional Administrative Data to improve the final quality assessment.
